From ab72528a4498251a702fa7693b51b9311b2432f8 Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Wed, 17 Feb 2010 11:18:57 +0100 Subject: [PATCH] [SCSI] zfcp: Move scsi result tracing decision to zfcp_dbf.h Move the decision which trace tag and trace level to use for the scsi result trace to zfcp_dbf.h. zfcp_dbf_scsi_result is already an inline function, so move the trace code there, simplifying the response handling in zfcp_fsf.c.
